Boy Scouts live by the motto "Be Prepared." However, nothing can prepare this group of young boys and their scoutmaster for what they encounter on a small, deserted island, as they settle down for a weekend of campfires, merit badges, and survival lessons. Everything changes when a haggard stranger in tattered clothing appears out of nowhere and collapses on the campers' doorstep. Before the night is through, this stranger will end up infecting one of the troop's own with a bioengineered horror that's straight out of their worst nightmares. Now stranded on the island with no communication to the outside world, the troop learns to battle much more than the elements, as they are pitted against something nature never intended…and eventually each other.
